History and truth are often out of synchronization (esp. in these days of pervasive propaganda/active manipulation of the population using mass communication technology). The chapters of the human story that played out 15,000 to 5,000 years ago in Africa/Europe/Near East/India are still being figured out by a combination of archeological, genetic, and linguistic research. Concerning the worship of "Earth/Mother Goddesses" vs. "Sky Gods" (e.g. Yahweh, Zeus, Thor, etc.) and the interactions of the different groups of people who preferred (and oftentimes forced upon others) their own visions of deity, if you want to engage rationally on this topic, I recommend researching and understanding (and contesting in an actual rational manner if you believe that the hypothesis is false) the "Kurgan Hypothesis."[1] There are some good books about it.
